SHUTTLE.

Application filed November 5, 1919.

To all whom it may concern:

Be it known that I, THOMAS MATLooB, an

Assyrian, residing at Paterson, in the county r entirely reliable and efficient, shall be very simple in construction and inexpensive to manufacture and readily applicable to ordinary shuttles.

Figure 1 is a fragmentary plan view of a shuttle embracing my improvement, the spindle being depressed;

Fig. 2 is a transverse sectional view on about the line 2-2 in Fig. 1, the spindle being elevated;

Fig. 3 shows. in longitudinal section a fragment of the quill and the device for holding the same;

Fig. 4c shows said device in elevation and the quill and spindle in transverse section; and

Fig. 5 shows a modified form of the device in elevation and in section.

The spindle a, fulcrumed on the pin a in the shuttle body 6, between the plates 0 (which are here shown as of the ordinary form, with jaws (Z for holding a quill having a head against slipping off the spindle, as by engaging the said head), is adapted to be held in its depressed position by a plate spring 6 shown in Fig. 2 of well-known form; a spring to hold the spindle thus depressed is not indispensable, but it is preferable.

f designates a tubular quill or cop tube made of some such yielding material as paper, paper .quills or tubes being new commonly used as the cores for wound packages in shuttles.

A crotched quill pinching member is pro vided and arranged under the spindle so that the latter, when depressed will enter its crotch and consequently jam the tube f of yielding material between the spindle and crotched member, more or less as shown in Fig. 4. Preferably this crotched member Specification of Letters Patent.

g, has its crotch formed with a more or less sharp edge It to bite into the material of the tube. A simple form of this crotched member is a strip of metal having its intermediate portion U-shaped and its extremities 2' bent off, preferably downwardly. It is best to arrange this member as near the butt of the spindle as possible, and to secure it in place I preferably anchor its legs or projections 2' between the jaws (Z of the plates 0 and the flanking portions of the shuttle body, said legs being in fact clamped between said jaws and the flanking portions.

It is not essential that the crotch be reduced to an edge. For example, the modified form 7' of the device shown in Fig. 5, will in many cases very well serve the pur pose, although it is simply a piece of wire bent to form the crotch 7c and suitable at taching portions Z and round in cross section; but it presents a narrow face in its crotch to the yielding tube, and in view of the pressure of the spindle and its tendency to jam the tube into the crotch it serves quite well to prevent the tube slipping off the spindle.

I do not wish to be limited to a securing device which is necessarily crotched in form. My device essentially constitutes a crosspiece underlying and close to the spindle, and if it presents a narrow face to the yielding tube and the spindle when depressed forces the tube with suflicient pressure against the cross piece the latter will more or less bite into the tube and prevent its slipping off the spindle.

Having thus fully described my inven tion, what I claim as new and desire to secure by Letters Patent is In combination, a shuttle body, a spindle pivoted therein on a transverse axis and movable to and from a position where it stands depressed in and extends substanti ally longitudinally of the shuttle body, and a crotched member having a projecting leg on each side of its crotch stationarily anchored in the shuttle body, said crotched member being arranged in position for the spindle to enter the same when the spindle is depressed, whereby a tubular quill on the depressed spindle may be jammed between the spindle and crotched member.

In testimony whereof I afiix my signature.

THOMAS MATLOOB.
